#30. "RE: Mastering the Nikon D90 - NikoniansPress Book" In response to In response to 29
Inside the front cover of my copy is a sticker directing the reader to the publisher's website (www.rockynook.com) to get corrections for pages 80-85. I seem to remember that the publisher also had a way to contact the author.
So, I would go to the publisher's website and make them aware of the errors that you have found. They can then post a correction sheet for downloading and make the changes in any future editions of the book.
